You should spend about 20 minutes on this task. The diagram below shows how energy is produced from coal. Summarize the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The figures show some design principles of a house with the aim of increasing the efficiency of energy usage and illustrating the way every layout works in different types of climates.

Overall

, there are two main seasons including cool and warm climates. In the lower temperatures, the building seems to be storage heat.

Whereas

, in the warmer situation, the building leads to the release of it. Looking at the information in detail, it can be seen that in the cool season, thermal materials are applied to allow

to store heat.

Therefore

, there is a big window which faces directly to the sun in order for to light pass the wall. On the opposite side of the window, the developer establishes an insulation system to reduce heat loss.

Thus

,

this

will stay warm even in heavy rain or snow. The second design consists of two primary designs.

Firstly

, in the days of hot climate, there are covers on every side of the wall to ensure that sunlight can not enter the inside of a room.

In addition

, external insulation plus reflection are installed to reduce the high temperature.

By contrast

, when night comes, windows as a ventilation are opened to maximise the air circulation.
